    Abstract: Endocrine disruptors (ED) are exogenous agents that interfere with the normal function of the endocrine system and they are considered environmental chemicals with estrogen-like and/or anti-androgenic activity with important impact on the reproductive axis. They act via nuclear receptors, non-nuclear steroid receptors, nonsteroidal receptors, orphan receptors, and different enzyme pathways involved in the biosynthesis and/or metabolism of steroids. The molecules identified as ED and sources of exposure are diverse and vary worldwide, including from natural chemicals found in human and animal food (the main source) up to synthetic chemicals, such as as solvents, plasticizers, pesticides, fungicides, pharmaceuticals etc. ED are incriminated in the occurrence of malignant tumors, birth defects, attention deficit disorders, cognitive impairment, brain development, deformations of the body (including limbs), disturbance of sexual development, menstrual irregularity, precocious puberty, feminizing or masculinizing effects, abortion, not least obesity and decreased fertility. The principles of action are still studied and controversial, therefore, it is difficult to determine the minimum level at which adverse effect occurs and further studies are required.

    Abstract: Once recombinant human erythropoietin (r-HuEPO) was introduced in daily practice, huge steps were made in combating the adverse effects induced by anemia in chronic kidney disease population. Still, r-HuEPO resistance and the doses ensuring the maximum therapeutic benefit remain matters of debate. The aim of our study was to assess the correlation between the presence and the degree of inflammation and the r-HuEPO requirements in chronic dialysis patients. We conducted a 2 years prospective study on 146 patients undergoing chronic dialysis treated with r-HuEPO. Based on their average CRP (C-reactive protein) levels, obtained from repeated samplings at 3 months interval, 3 groups were formed; we noted in each group the average values of r-HuEPO prescribed to achieve the optimum hemoglobin levels according to the dialysis best practice guidelines and all the adverse effects of the therapy. A direct correlation was observed between CRP levels and r-HuEPO requirements in the first 2 groups of patients (CRP under 6 mg/L and CRP values 6-20 mg/L), with significant increase in r-HuEPO doses between groups (p [ 0.001); the third group, CRP values over 20 mg/dL, showed a minor, insignificant increase in average r-HuEPO doses compared to mild inflammation group (p = 0.199) and more adverse effects of the therapy (p [ 0.05). Inflammation is an important determinant of anemia in chronic dialysis patients and can induce an increase in the doses of r-HuEPO. However, prescribing excessive r-HuEPO doses is not the answer in severe inflammatory status, due to lack of response and possible adverse effects.
